To all whom it may concern:

Be it known that I, WILLIAM PACEY, a subject of King George. V of GreatBritain, residing at 40 Bowling Street, Dunedin, New Zealand, haveinvented certain new and useful Improvements in or Relating to HandShears, of which the following is a specification.

This invention relates to shears, a tool used for hand shearing sheep,and on occasions by gardeners for trimming the edges of grass lawns andthe like places.

The object .of my means whereby the blades of shears may be easily andquickly detached from the handle for sharpening purposes, or a new bladeor blades easily and expeditiously fitted in position on the handle,whereby the blades may be interchangeable The invention will be clearlyunderstood from the following detailed description and the illustrationaccompanying the specifica tion in which:

Figure l is a perspective view of the invention, all the parts beingassembled.

Figure 2.is a part perspective view enlarged to more clearly illustratethe method of attaching the blade to the handle.

Figure 3 is a view showing the cross sectional contour of the handle andthe blade shank.

According to this invention, the usual soring l forming the bow or buttof the handle may be used to holdthe blades normally open, instead ofthe handle portion 2 and 2 having the usual cross sectional form, theedges 2 and 2 are curled inwards to form a bead, forming together asocket, wherein the shank 3 of the blade 4 is housed, the said shank 3is convex on its outer surface 3 and concave on its inner surface 3 theconvexity of its outer surface conforming with the concaveform of'theinner surface of the handle part 2 and 2 and the edges 3 and 3 of thesaid shank 3 are formedv in a manner to engage the inner surface of thebeads 52 and 2 .and thehandle parts 2 and 2 so that when all parts areassembled the blade will, be rigidly retained.

There is a catch at provided, forming part of the blade 4 the said catchhas a resilient member a under the influence of which the said catch 4is held normally inclined towards the shank 3 of the blade and theshoulders 4 and t of the shank 3, and is adapted to engage withpreferably invention is to provide ends of pushing the blade vsuchextensions and cooperate with shoulders 2 and 2 formed by boring a hole2 in the said handle parts 2 and 2 here is'a slot 2 from't-he ends 2thereof to the hole 2 joinlng with the said hole approximately at theshoulders 2 and 2 the said slots are provided for the purposeofpermitting the catch 4 and its flush with the outside surface of thehandle parts 2 and 2 soas not to chafe the hands of the user, and toment of the blade.
